Mode

Selects the operating mode for the VOR modulation signal.

"Norm"

VOR modulation is active.

"Var"

Amplitude modulation of the output signal with the VAR signal compo-

nent (30Hz signal content) of the VOR signal. The modulation depth

corresponds to the value set under VAR Depth.

"Subcarrier"

Amplitude modulation of the output signal with the unmodulated FM

carrier (9960Hz) of the VOR signal. The modulation depth corre-

sponds to the value set under Subcarrier Depth.

"Subcarrier +

FM"

Amplitude modulation of the output signal with the frequency-modula-

ted FM carrier (9960Hz) of the VOR signal. The frequency deviation

corresponds to the value set under REF Deviation, the modulation

depth corresponds to the value set under "Subcarrier Depth".
